Major Report Prompts Warnings That the Arctic Is Unraveling
The polar region is warming more than twice as fast as the rest of the
planet

The Arctic is warming more than twice as fast as the rest of the planet,
suggests a huge assessment of the region. The warming is hastening the
melting of Arctic ice and boosting sea-level rise
<http://www.nature.com/news/climate-science-rising-tide-1.13749>.

The report, compiled by more than 90 scientists, documents the myriad changes
already under way across the Arctic
<http://www.nature.com/nature/journal/v499/n7459/pdf/499401a> because of
climate change—from declining sea ice and melting glaciers to shifting
ecosystems and weather patterns. From 2011 to 2015, the assessment finds,
the Arctic was warmer than at any time since records began around 1900 (see
'Arctic warming
<http://www.nature.com/news/huge-arctic-report-ups-estimates-of-sea-level-rise-1.21911#graphic>
').

Sea ice continues to decline
<http://www.nature.com/news/incredibly-thin-arctic-sea-ice-shocks-re>, and
the extent of snow cover across the Arctic regions of North America and
Eurasia each June has halved as compared to observations before 2000.

The findings come from the Snow, Water, Ice, and Permafrost in the Arctic
report
<https://www.amap.no/documents/doc/Snow-Water-Ice-and-Permafrost.-Summary-for-Policy-makers/1532>,
a comprehensive assessment compiled every few years by the Arctic
Monitoring and Assessment Programme, the scientific body that reports to
the governments that make up the Arctic Council, a forum for issues
affecting the region. The last assessment came out in 2011
<https://www.amap.no/documents/doc/arctic-climate-issues-2011-changes-in-arctic-snow-water-ice-and-permafrost/129>
.
Observation to action

“The take-home message is that the Arctic is unravelling,” says Rafe
Pomerance, who chairs a network of conservation groups called Arctic 21 and
was a deputy assistant secretary of state for environment and development
under US President Bill Clinton. “The fate of the Arctic has to be moved
out of the world of scientific observation and into the world of government
policy.”

The report increases projections for global sea-level rise
<http://www.nature.com/news/climate-science-rising-tide-1.13749>, which
takes into account all sources of melting including the Arctic. Their new
minimum estimates are now almost double those issued by the
Intergovernmental Panel on Climate Change (IPCC) in 2013
<http://www.nature.com/news/ipcc-despite-hiatus-climate-change-here-to-stay-1.13832>
for
some emissions scenarios. In fact, the latest calculations suggest that the
IPCC's middle estimates for sea-level rise should now be considered minimum
estimates.

In one scenario, which assumes that carbon emissions rise slightly above
the goals set by the 2015 Paris climate agreement—but still see a
considerable reduction—sea levels would increase by at least 0.52 metres by
2100, compared with 2006, the Arctic report says. Under a business-as-usual
scenario, the minimum increase would be 0.74 metres.

Although aggressive reductions in greenhouse-gas emissions will make a
crucial difference by the end of the century, dramatic changes are still
likely over the next few decades, says Morten Skovgård Olsen, who
coordinated the assessment and leads the Danish Ministry of Energy,
Utilities and Climate’s Arctic programme.

“The Arctic that you will have by mid-century will be very different from
the Arctic that we see today,” he says.
